ABSTRACT:
An intake system for an internal combustion engine is provided which comprises a variable valve control apparatus capable of variably and continuously controlling the amount of intake air of an internal combustion engine by varying valve lift characteristics of an intake valve, a collector fluidly connected with a plurality of intake passages for cylinders of the internal combustion engine, and a pressure control mechanism for producing within the collector a vacuum that increases with increase of one of the amount of intake air, engine speed and engine load of the internal combustion engine.
